—We analyzed diff erences in wing morphology between sexes and among age classes of Western Sandpipers (Calidris mauri) to assess possible relationships with diff erential migration, acrobatic aerial displays, and potential vulnerability to predation, using size-constrained component analysis. Data on wing morphology of all four sex and age classes were available from birds spending the nonbree...

admitted to hospital for thunderclap headache, blurred vision and hypertension. Based on clinical manifestations, diagnostic work-up and follow-up, the authors diagnosed the case as posterior reversible encephalopathy syndrome (PRES) [1]. We agree that PRES should be considered in this case, while diff erential diagnosis such as subarachnoid hemorrhage (SAH) requires further investigation and e...

in this paper, we prove the existence of the solution for boundary value prob-lem(bvp) of fractional dierential equations of order q 2 (2; 3]. the kras-noselskii's xed point theorem is applied to establish the results. in addition,we give an detailed example to demonstrate the main result.

in this work, we have applied elzaki transform and he's homotopy perturbation method to solvepartial dierential equation (pdes) with time-fractional derivative. with help he's homotopy per-turbation, we can handle the nonlinear terms. further, we have applied this suggested he's homotopyperturbation method in order to reformulate initial value problem. some illustrative examples...

We consider the construction of geometric integrators in the class of RKMK methods. Any di erential equation in the form of an in nitesimal generator on a homogeneous space is shown to be locally equivalent to a di erential equation on the Lie algebra corresponding to the Lie group acting on the homogenous space. This way we obtain a distinction between the coordinate-free phrasing of the di er...

Diff ering lifehistory strategies may act as a constraint on reproductive expression that ultimately limits the ability of individual species to respond to changes in the magnitude or frequency of environmental variation, and potentially underlies the variation oft en inherent in phenotypic and evolved responses to anthropogenic change. Alternatively, if there are environmental cues that predic...

Pain represents a frequent symptom in various psychiatric disorders ranging from so called psychogenic or somatoform disorders to depression, to schizophrenia and to organic brain syndromes including dementia. Th alamic lesions are long known to induce painful symptoms. Th e cortex is involved in pain awareness. Th e locus coeruleus modulates pain perception. Various facets of pain in a range o...

Edema is defi ned as abnormal accumulation of fl uid in the interstitium. Diff erential diagnosis of generalized edema is very broad. Most often, renal and cardiac causes lead to generalized edema. The potential gastrointestinal causes of edema are liver failure and protein losing enteropathy including celiac disease and protein malnutrition. Generalized edema is rarely an initial manifestation...
